Question

Quizplus · Accepted Answer

Cilia are hairlike structures located in the respiratory tract which help to remove foreign substances and maintain a healthy respiratory system. They are responsible for removing debris, pollutants and other substances from the lungs, and are essential for preventing respiratory infections. Phagocytic cells and macrophages are both types of immune cells that work to remove foreign substances from the lungs, but they do not have hairlike structures. Enzymes are biological molecules that catalyze chemical reactions, and are not directly involved in the removal of foreign substances from the lungs.
